Question

我在this site的帮助下编写了以下代码。但是因为我在我的设备中使用了PHPRunner。我按如下方式更改了url：

http://127.0.0.1:8080/apps/connection.php

但是当我点击按钮显示来自php server的输入时，输入将不会从php文件显示到Android屏幕。

public class MainActivity extends Activity {
    TextView content;
    EditText fname, email, login, pass;
    String Name, Email, Login, Pass;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        content    =   (TextView)findViewById( R.id.content );
        fname      =   (EditText)findViewById(R.id.name);
        email      =   (EditText)findViewById(R.id.email);
        login      =    (EditText)findViewById(R.id.loginname);
        pass       =   (EditText)findViewById(R.id.password);


        Button saveme=(Button)findViewById(R.id.save);

        saveme.setOnClickListener(new Button.OnClickListener(){

            public void onClick(View v)
            {
                try{

                    // CALL GetText method to make post method call
                    GetText();
                }
                catch(Exception ex)
                {
                    content.setText(" url exeption! " );
                }
            }
        });
    }

    // Create GetText Metod
    public  void  GetText()  throws UnsupportedEncodingException
    {
        // Get user defined values
        Name = fname.getText().toString();
        Email   = email.getText().toString();
        Login   = login.getText().toString();
        Pass   = pass.getText().toString();

        // Create data variable for sent values to server

        String data = URLEncoder.encode("name", "UTF-8")
                + "=" + URLEncoder.encode(Name, "UTF-8");

        data += "&" + URLEncoder.encode("email", "UTF-8") + "="
                + URLEncoder.encode(Email, "UTF-8");

        data += "&" + URLEncoder.encode("user", "UTF-8")
                + "=" + URLEncoder.encode(Login, "UTF-8");

        data += "&" + URLEncoder.encode("pass", "UTF-8")
                + "=" + URLEncoder.encode(Pass, "UTF-8");

        String text = "";
        BufferedReader reader=null;

        // Send data
        try
        {

            // Defined URL  where to send data
            URL url = new URL("http://127.0.0.1:8080/apps/connection.php");

            // Send POST data request

            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
            OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
            wr.write( data );
            wr.flush();

            // Get the server response

            reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line = null;

            // Read Server Response
            while((line = reader.readLine()) != null)
            {
                // Append server response in string
                sb.append(line + "\n");
            }


            text = sb.toString();
        }
        catch(Exception ex)
        {

        }
        finally
        {
            try
            {

                reader.close();
            }

            catch(Exception ex) {}
        }

        // Show response on activity
        content.setText( text  );

    }

和

<?php 

       $name   = urldecode($_POST['name']);
       $user   = urldecode($_POST['user']);
       $email  = urldecode($_POST['email']);
       $pass   = urldecode($_POST['pass']);

       print " ==== POST DATA =====
       Name  : $name
       Email : $email
       User  : $user
       Pass  : $pass"; 

 ?>

Answer 1

您在本地主机上进行此操作。使用命令 ipconfig 检查CMD中的地址。然后将地址从 127.0.0.1 更改为您计算机的加法器。您必须知道您的模拟器和Android设备在localhost中也不起作用。您必须使用计算机的IP。

就我而言，它是192.168.103

Answer 2

您的代码是正确的，它会起作用。只有您在AndroidManifest.xml中添加以下代码：

 <uses-permission android:name="android.permission.INTERNET"/>

输入将不会从php文件显示到android屏幕
